Gigabit links to the home were cheap in South Korea 20 years ago, something like $50USD/month, IIRC. The population is so dense, it was comparatively quick and easy to put in the infrastructure.
Some of the fastest pirate FTP sites in the world were .kr at the time, it was crazy seeing 125MB/sec inter-site transfers back then.
The ops must've set the machines up with a /dev/shm ramdisk or similar for uploads. There were no SSDs those days, so no way to even write at 125MB/sec, unless you had an unreasonably large Raid-0 array of WD Raptor HDDs, also possible.
